Contour plots
These plots are vertical X-Z cross-sections along the two diagonals of the parameters involved in the intercomparison. They are monthly means for the daily hours 00, 03, 06, 09, 12, 15, 18 and 21 UTC. Please note that Hawaii time (in the middle of the section) lags UTC time by 10 hours.

Diurnal cycle of single-level-parameters
These figures show the monthly average diurnal cycle of the single-level parameters, for each of the three months and for both diagonal sections (1 and 2, see the case description for more details). The observational data is obtained from the ISCCP dataset.
